Please tune in tonight, Sept. 28 for 60 Minutes and meet Jack Ma, the charismatic founder of Alibaba, the e-commerce giant that just issued the biggest public offering of its stock in Wall Street history. When I first met him a year and a half ago, I was immediately struck by the notion that Ma is a giant in a small frame, as you can see from our joint photo with his Alibaba team. And yes, that’s my son Daniel on the right, who joined my 60 Minutes team while we were in China to work as a translator, fixer and as my personal shlepper. Never had such a qualified or attentive aide-de-camp. The correspondent is Lara Logan.
